During installation of mingw, at least, the git directories change, so
we need to reset the core.autocrlf config to false.
Once we finish checking out submodules, check that the line endings are
\n and not \r\n.
use visitor for #[structural_match] check
This changes the code so that we recur down the structure of a type of a const (rather than just inspecting at a shallow one or two levels) when we are looking to see if it has an ADT that did not derive `PartialEq` and `Eq`.

This enforces that eof() must be called to get the String out, and
generally is better from an API perspective. No users of pretty printing
pre-allocate the buffer.
This function took too many arguments and are simple on the inside;
inlining them makes complexity go down.
hir::print's copy is unfortunately used from librustc_driver so inlining
it is not as straightforward.
Miri: Provide pointer forcing methods for MemPlace and Op
These are useful when one wants to to a lot of work with some place or operand and not to int-to-ptr casts all the time. In particular, this is needed to fix some test failures in Miri: we need to normalize before starting a visitor that walks a run-time value, so that we can later be sure (during the visitor walk) that we have a proper `Pointer`.
Also see the Miri side at https://github.com/rust-lang/miri/pull/830.

Prepare for LLVM 9 update
Main changes:
* In preparation for opaque pointer types, the `byval` attribute now takes a type. As such, the argument type needs to be threaded through to the function/callsite attribute application logic.
* On ARM the `+fp-only-sp` and `+d16` features have become `-fp64` and `-d32`. I've switched the target definitions to use the new names, but also added bidirectional emulation so either can be used on any LLVM version for backwards compatibility.
* The datalayout can now specify function pointer alignment. In particular on ARM `Fi8` is specified, which means that function pointer alignment is independent of function alignment. I've added this to our datalayouts to match LLVM (which is something we check) and strip the fnptr alignment for older LLVM versions.
* The fmul/fadd reductions now always respect the accumulator (including for unordered reductions), so we should pass the identity instead of undef.
Open issues:
* https://reviews.llvm.org/D62106 causes linker errors with ld.bdf due to https://sourceware.org/bugzilla/show_bug.cgi?id=24784. To avoid this I've enabled `RelaxELFRelocations`, which results in a GOTPCRELX relocation for `__tls_get_addr` and avoids the issue. However, this is likely not acceptable because relax relocations are not supported by older linker versions. We may need an LLVM option to keep using PLT for `__tls_get_addr` despite `RtLibUseGOT`.
The corresponding llvm-project PR is https://github.com/rust-lang/llvm-project/pull/19.

Target::arch can take more than listed options
A list of options in a comment like this is almost guaranteed to become out of date: right now it is missing "riscv32" and "riscv64" and perhaps other architectures as well.
Add Iterator::partition_in_place() and is_partitioned()
`partition_in_place()` swaps `&mut T` items in-place to satisfy the
predicate, so all `true` items precede all `false` items. This requires
a `DoubleEndedIterator` so we can search from front and back for items
that need swapping.
`is_partitioned()` checks whether the predicate is already satisfied.
